Kelly Osbourne sends scathing message to ex Sid Wilson after his Slipknot firing

Kelly Osbourne demanded child support from her ex Sid Wilson after he was fired from Slipknot after nearly 30 years in the band.

“Wake the f–k up and take some responsibility I will not take your s–t anymore! I’m done,” the “Osbournes” alum, who shares 3-year-old son Sidney with the DJ, wrote on her Instagram Stories.

“I want to be happy and I have a beautiful son to raise. Leave me alone. Let me heal. I can’t protect you from yourself anymore,” she added.

In another post, Osbourne, 41, wrote: “Also while I’m at it can I have my dogs back and all my possessions. Oh yeah and maybe some child support?”

The former “Fashion Police” host also shared cryptic messages about someone being “guilty.”

“Strange how the loudest defense of the guilty is rarely innocence … It’s distraction. When the mask slips, they don’t face the mirror they throw it at someone else,” she wrote.

“I also heard that when you break a mirror you get 7 years bad luck! Or is that just karma? This is why I always take accountability. As they say some are sicker than others,” Osbourne added.

The mom of one also shared an inspirational quote about mothers protecting their children.

“My son’s little heart once beat right beside mine. So trust me when I say … I will protect it all costs,” the Everyday Motherhood quote read.

“My job is to protect my kids. Not your feelings. Not your expectations. Not judgements I didn’t ask for,” read the message from Inex Digital Wealth.

“My responsibility is to protect their wellbeing. Their nervous systems. Their emotional safety. I will choose them every single time. Over anyone. Over anything,” it added.

Page Six has reached out to Wilson and a rep for Osbourne but did not immediately hear back.

Osbourne’s pointed messages come days after Wilson, 49, was booted from his legendary band after 28 years with them.

TMZ reported that the rockstar was notified last Friday that he had been permanently let go from Slipknot.

The outlet claimed the band had had enough of Wilson’s behavior — especially the way he allegedly treated his bandmates.

Slipknot guitarist Jim Root shared a cryptic note to fans after his bandmate was fired from the heavy metal group.

“Don’t believe everything you read,” he wrote via his Instagram Stories on Sunday.

“Think. Take a breath. Sit with it for awhile (sic). Maybe. Just maybe even wait until there’s more information.”

Wilson, who joined Slipknot in 1999 and was one of its nine original members, has not publicly responded about his termination.

He and Osbourne began dating in 2022 and welcomed their son, Sidney, that November.

In July 2025, Wilson proposed to the former reality star backstage during her dad Ozzy Osbourne’s final Black Sabbath show.

The exes called off their engagement in March after four years together.
